How to solve the problem of cashier computer keyboard failure

All keys of Yinbao are malfunctioning

The interfaces are different. The scanning gun interface of Yinbao computer does not match the interface of the computer. The size is different, resulting in the keyboard and code scanning. The gun didn't respond. If a conflict occurs, the installation of the computer's SCSI device is complicated. If there is no SCSI card on the computer, it is easy to cause a hardware conflict, causing the scanner and keyboard to be unable to be recognized.

First check whether the touch screen is normal, because the mouse can be used to rule out software problems, we only need to start with the hardware. Re-install the touch screen driver, restart the computer and try again, it should be fine.

The solution to the problem that the Yinbao cash register power supply cannot be turned on is as follows: 1. First, check whether the power supply is normal. 2. If there is no response when pressing the power button, it may be that the built-in power supply of the cash register is broken or the external adapter is broken. 3. When you press the power button, you can hear the fan sound, and then it goes off by itself after a while. Maybe the motherboard or power supply is bad.
